Olive-sided Flycatcher

Although a cold one may be in order at the end of a long day in the field, this is not the call to head to the pub, but the call of an Olive-sided Flycatcher — at least it’s the mnemonic device that we ornithologists use to help remember its song. While I find it the most enticing of the mnemonics, it is certainly not the strangest. That distinction would go to the song of the Warbling Vireo, which we represent as “if I sees you I will seize you and I’ll squeeze you till you squirt!”
